A variety of hinges may be utilized, including a mono-axial hinge, a bi-axial hinge, a spherical hinge, or any other type of universal joint.
Description
- 1. Field of the Invention
- The present invention relates to solar lights. In particular, the present invention relates to solar collectors for solar lights.
- 2. Description of the Prior Art
- Solar powered lights have been around for many years. The solar collector is typically installed on the top of the housing.
- Because the housing is usually positioned so that the solar powered light illuminates in a particular direction, the solar collector is rarely positioned to maximize the solar energy from the sun.
- For these reasons, many shortcomings remain in the area of solar powered lighting.
- There is a need for a hinged solar collector that can be adjusted to maximize the collection of solar energy, regardless of the position of the housing of the solar powered light.
- Therefore, it is an objective of the present invention to provide a hinged solar collector that can be adjusted to maximize the collection of solar energy, regardless of the position of the housing of the solar powered light.
- The above objective is achieved by providing a solar collector that is positioned on a post that extends up from the housing of the solar powered light. The post includes a hinge that allows the solar collector to rotate about two different axes. This allows the solar collector to be positioned so that it can maximize the collection of solar energy, regardless of the direction or orientation of the housing.
- The above as well as additional objectives, features, and advantages will become apparent in the following description.
- The novel features believed characteristic of the invention are set forth in the appended claims.

FIGS. 21 through 24 depict a spotlight with a hinged solar collector. - Referring to
FIGS. 1 and 2 depict one embodiment of a hinged solar collector for a solar powered light is illustrated. As is shown asolar collector unit 11 is positioned at the top portion of apost 13.Solar collection unit 11 includes a conventionalsolar panel 12 and conventional wiring and circuitry (not shown) to allow the solar energy collected by solar panel to be converted into electrical energy and used to power or charge a solar poweredlight 15 or rechargeable battery (not shown).Post 13 is rotatably connected to ahousing 17 of solar poweredlight 15 so that solar collector unit may rotate relative tohousing 17.Post 13 includes a hinge means 19 that allowssolar collector unit 11 to pivot about the lower portion ofpost 13 and rotate relative tohousing 17. This configuration allowssolar collector unit 11 to be positioned at a wide variety of angles relative tohousing 17. - Because
solar collector unit 11 can be positioned independent ofhousing 17,solar collector unit 11 can be oriented so as to maximize its collection of solar energy, andhousing 15 can be oriented to illuminate a desired object or area. This enablessolar panel 12 to be perpendicular or more nearly perpendicular to sunlight rays while solar poweredlight 15 is in charging mode, while enabling, without need of later adjustment, or with less adjustment required by a user, solar poweredlight 15 to be aimed and cast in lighting mode in a position conducive to applications used by outdoor spotlights, such as aimed at a statue, tree or mailbox, for a purpose of decorative or utilitarian effect. - Although hinge means 19 is shown as a mono-axial hinge, it should be understood that a bi-axial hinge, a spherical hinge, or any other type of universal joint could also be used. It will be appreciated additional hinge means and extensions may also be utilized to achieved the desired mobility of
solar collector unit 11. - In the preferred embodiment,
post 13 includes one or more internal stop means that limit the rotation ofpost 13. This prevents damage to any wiring that may be installed withinpost 13. - A lighting array utilizing light housings with attached solar collectors has several benefits.
- First, by eliminating the need for a separate solar collector assembly, it simplifies installation by reducing labor and by eliminating extra wires that could become tangled and damaged.
- Second, by eliminating the separate collector assembly, the number of visual components in the lighting array is reduced, and improving the aesthetics of the array.
- Third, each collector can be uniquely positioned to maximize energy collection, given each collector's own position and light obstructions, allowing the array as a whole to collect the maximum possible amount of solar energy throughout the day. A single solar collector assembly will not track the sun's position throughout the day, so its collection efficiency will be reduced during certain periods of the day.
- Fourth, by electrically connecting each individual light assembly to the array, each solar collector can contribute to the total energy collection and each light can share the stored energy, allowing each light to have the same illumination performance.
- In some cases, the use of an additional, separate solar collection assembly can be beneficial.
- First, when the lights are positioned for proper illumination of a scene, the lights may not be in ideal positions to collect solar energy, or their view of the sun may be blocked by obstructions. A separate solar collector assembly allows additional energy collection in this case.
- Second, it may be possible to put a separate solar collector assembly out of view of the scene, improving the aesthetics of the lighting array and scene.
- Referring to
FIG. 10 , a prior art example of a solar poweredlight 15 is shown. As is shown, alight housing 17 is positioned at thetop portion 21 of a post. Post includes a hinge means 23 that allows light housing to pivot about thelower portion 25 of post. Lower portion of post is rotatably connected 27 toground stake 29 which provides support for thelight housing 17. This configuration allowslight housing 17 to be positioned at a wide variety of angles relative toground stake 29. - Referring to
FIG. 11 , an alternate embodiment of a hinged solar collector for a solar powered light is illustrated. As is shown asolar collector unit 31 is positioned at the top portion of apost 33.Solar collection unit 31 includes a conventionalsolar panel 12 and conventional wiring and circuitry (not shown) to allow the solar energy collected by solar panel to be converted into electrical energy and used to power or charge a solar powered light or rechargeable battery (not shown).Post 33 includes a spherical hinge means 35 that allowssolar collector unit 31 to pivot and rotate about the lower portion ofpost 33 and rotate relative tolight housing 17. This configuration allowssolar collector unit 31 to be positioned at a wide variety of angles relative tohousing 17. - Referring to
FIG. 12 , a prior art example of a solar collector assembly is shown. As is shown, asolar collector unit 31 is positioned at thetop portion 21 of a post. Post includes a hinge means 23 that allows collector to pivot about thelower portion 25 of post.Lower portion 25 of post is rotatably connected 27 toground stake 29 which provides support for the collector. The solar collector can be positioned independent of ground stake to maximize its collection of solar energy which is typically perpendicular to sunlight rays. - Referring to
FIG. 13 , a solar powered lighting array is shown. Asolar collector assembly 41 is electrically attached to an array of solar powered lights 15. It should be understood that the lighting array may utilize one ormore lights 15, and the array may utilize one or moresolar collector assemblies 41. The lights can be individually located and oriented to illuminate a desired object, objects or area, while the solar collector assembly may be independently located and oriented to maximize the collection of solar energy. - Referring to
FIG. 14 , a solar powered lighting array is shown. Asolar collector assembly 41 is electrically attached to an array of solar poweredlight assemblies 39, eachlight assembly 39 being comprised of a solar powered light 15 with an attachedsolar collector unit 31. It should be understood that the lighting array can utilize one or morelight assemblies 39, and can also utilize one or moresolar collector assemblies 41. Further, the array can utilize both solarlight assemblies 39 with attached solar collectors andlights 15 without attached collectors. Even though the individual solar light assemblies contain attached solar collectors, the addition ofsolar collectors assemblies 41 allows additional energy collection in the case that the lights may not receive sufficient solar energy in their unique locations and positions. Also, a separate collector assembly allows the collector assembly to be put out of view of the lights which are positioned relative to a scene interest which is in view. - Referring to
FIG. 15 , a solar powered lighting array is shown. In this embodiment, solar poweredlight assemblies 39 are electrically connected. It should be understood that the lighting array can utilize both solarlight assemblies 39 with attached solar collectors andlights 15 without attached collectors. By utilizing solar light assemblies with attached solar collectors, the installation of the array is simplified by eliminating a separate solar collector assembly and the extra wiring that provides an additional opportunity for tangled and damaged wires. - Referring to
FIGS. 16 a thru 16 c, several embodiments of single-hinge joints are shown. - Referring to
FIG. 16 a, one embodiment of a mono-axial hinge joint is shown.Upper portion 101 of post is connected to solar collector andlower portion 105 is rotatably connected 107 to light housing.Upper portion 101 is connected tolower portion 105 with ahinge joint 103. Post may be limited by one or more internal stop means that limit the rotation of post relative to housing. This prevents damage to any wiring that may be installed within post.Hinge 103 may be limited by one or more internal stop means that limit the range of rotation ofupper portion 101 relative tolower portion 105. In addition,hinge 103 may have internal means such as a crenellated surface that restricts rotation to discreet positions. - Referring to
FIG. 16 b, another embodiment of a mono-axial hinge joint is shown. -
Upper portion 111 of post is connected to solar collector andlower portion 115 is rotatably connected 117 to light housing.Upper portion 111 is connected tolower portion 115 with ahinge joint 113. Post may be limited by one or more internal stop means that limit the rotation of post relative to housing. This prevents damage to any wiring that may be installed within post.Hinge 113 may be limited by one or more internal stop means that limit the range of rotation ofupper portion 111 relative tolower portion 115. In addition,hinge 113 may have internal means such as a crenellated surface that restricts rotation to discreet positions. - Referring to
FIG. 16 c, an embodiment of a spherical joint is shown.Upper portion 121 of post is connected to solar collector,lower portion 125 is connected to light housing, andupper portion 121 is connected tolower portion 125 with a spherical joint 123. While the spherical joint 123 could allow rotation ofupper portion 121 about its own axis,lower portion 125 may optionally be rotatably connected atconnector 127 to light housing. Spherical joint may be limited by one or more internal stop means that limit the angular deviation of upper portion relative to lower portion. Also, spherical joint may be limited by one or more internal stop means that limit the rotation of upper portion about its axis, androtatable connection 127 may be limited by one or more internal stop means that limit the rotation of lower portion about its axis. These limiting means prevent damage to any wiring that may be installed within post. - Referring to
FIG. 16 d, another embodiment of a mono-axial hinge joint is shown.Upper portion 131 of post is connected to solar collector andlower portion 135 is rotatably connected atconnector 137 to light housing.Upper portion 131 is connected tolower portion 135 with ahinge joint 133. Post may be limited by one or more internal stop means that limit the rotation of post relative to housing. This prevents damage to any wiring that may be installed within post.Hinge 133 may be limited by one or more internal stop means that limit the range of rotation ofupper portion 131 relative tolower portion 135. In addition,hinge 133 may have internal means such as a crenellated surface that restricts rotation to discreet positions. - Referring to
FIGS. 17 a thru 17 c, several embodiments of dual-hinge joints are shown. - A dual-hinge joint has benefits over a single hinge joint. First, a dual-hinge joint with a connecting portion may allow more freedom of movement of a solar collector relative to the light housing by eliminating interference between the collector and light housing that results from their overall dimensions. For example, when the connecting portion is short, the edge of the solar collector may interfere with the light housing with only a small amount of angular deviation of the collector. By lengthening the connecting portion, the solar collector may be able to deviate by 90 degrees or more before encountering interference with the light housing.
- Second, in the case of a bi-axial hinge, the axes of each hinge need not be parallel. This allows the post and hinge design to be simplified by eliminating the need for a rotating coupling between the post and collector or post and light housing. For example, by making the axis of one hinge orthogonal to the axis of the second hinge, a full range of movement can be achieved, allowing the collector to be directed in any direction that the mono-axial hinge design with rotating coupling can achieve.
- Referring to
FIG. 17 a, one embodiment of a bi-axial hinge joint is shown.Upper portion 203 of post may be rotatably connected 201 to solar collector, andlower portion 211 may be rotatably connected 213 to light housing. Upper portion is connected tomiddle portion 207 with a hinge joint 205, and middle portion is connected to lower portion with ahinge joint 209. Post may be limited by one or more internal stop means that limit the rotation of post relative to housing and the rotation of the solar collector relative to post. This prevents damage to any wiring that may be installed within post. Hinges may be limited by one or more internal stop means that limit the range of rotation of middle portion relative to upper portion and lower portion. In addition, hinges may have internal means such as a crenellated surface that restricts rotation to discreet positions. - Referring to
FIG. 17 b, another embodiment of a bi-axial hinge joint is shown. -

Upper portion is connected tomiddle portion 227 with a hinge joint 225, and middle portion is connected tolower portion 231 with ahinge joint 229. Post may be limited by one or more internal stop means that limit the rotation of post relative to housing and the rotation of the solar collector relative to post. This prevents damage to any wiring that may be installed within post. Hinges may be limited by one or more internal stop means that limit the range of rotation of middle portion relative to upper portion and lower portion. In addition, hinges may have internal means such as a crenellated surface that restricts rotation to discreet positions. - Referring to
